The Mexican flag is a vertical tricolor of green, white, and red, with the national coat of arms in the center of the white stripe. It is one of Mexico’s most important national symbols, along with the national anthem and the coat of arms itself.

For citizenship learners, the key point is that the flag combines modern national identity with older historical memory. The three colors come from the early independence era, while the coat of arms refers to the Mexica founding legend of Tenochtitlan, the city that became the foundation of Mexico City. Together, the flag connects independence, national unity, and Indigenous roots.
